Filtration and purification system and method therefor

Abstract

An automatic water filtration and purification system will allow a continuous water flow to downstream fixtures while simultaneously and automatically regularly flushing and cleaning in-path filter media. The automatic water filtration and purification system has at least one filter to remove impurities from a water in-path through-put. A cleaner is coupled to the at least one filter to clean the at least one filter. A controller is coupled to the at least one filter to regulate automatic operation of the cleaner wherein continuous operation of water flow to fixtures downstream of the at least one filter is essentially uninterrupted during the operation of the cleaner and the controller.

1. An automatic water filtration and purification system for light industrial and home installations, having continuous water flow to a fixture coupled thereto, while simultaneously and automatically regularly flushing and cleaning in-path filter media, comprising, in combination:
 a course filter assembly coupled to the bypass valve; 
 a fine filter assembly coupled in series to the course filter assembly; 
 an ultraviolet lamp assembly coupled series with the fine filter assembly; 
 a respective flushing control valve coupled to a flushing port located on each of the course filter assembly and the fine filter assembly; 
 a bypass valve coupled to a water line for diverting water to the fixture without passing through the course and fine filter assemblies; and 
 a programmable control unit connected to the flushing control valves wherein the programmable control unit comprises a sequentially energized flushing control valve timer electrically connected to the flushing control valves for automatically and regularly flushing and cleaning the course and fine filter assemblies. 
 
     
     
       2. The automatic water filtration and purification system in accordance with  claim 1  further comprising a valve filter coupled downstream of at least one of the flushing control valves. 
     
     
       3. The automatic water filtration and purification system in accordance with  claim 2  further comprising an air bleed valve coupled to the bypass valve to remove air from the automatic water filtration and purification system.
